2014-08-04checker: ignore fields marked unusedAmit Shah1-4/+50
While comparing qemu-1.0 json output with qemu-2.1, a few fields got marked unused. These need to be skipped over, and not flagged as mismatches. For handling unused fields, the exact number of bytes need to be skipped over as the size of the unused field. Currently, only the term "unused" is matched. When more field names turn up, this will have to be updated based on the whitelist matching method to match more such terms. Signed-off-by: Amit Shah <amit.shah@redhat.com>

2014-08-01qemu: support xen hvm direct kernel bootChunyan Liu4-0/+38
qemu side patch to support xen HVM direct kernel boot: if -kernel exists, calls xen_load_linux(), which will read kernel/initrd and add a linuxboot.bin or multiboot.bin option rom. The linuxboot.bin/multiboot.bin will load kernel/initrd and jump to execute kernel directly. It's working when xen uses seabios. During this work, found the 'kvmvapic' is in option_rom list, it should not be there in xen case. Set s->vapic_control = 0 in xen_apic_realize() to handle that.

2014-08-01tap-bsd: implement a FreeBSD only version of tap_openRoger Pau Monne1-1/+69
The current behaviour of tap_open for BSD systems differ greatly from it's Linux counterpart. Since FreeBSD supports interface renaming and tap device cloning by opening /dev/tap, implement a FreeBSD specific version of tap_open that behaves like it's Linux counterpart. This is specially important for toolstacks that use Qemu (like Xen libxl), in order to have a unified behaviour across suported platforms.

2014-07-29pc: acpi: generate AML only for PCI0 devices if PCI bridge hotplug is disabledIgor Mammedov1-5/+21
Fixes migration regression from QEMU-1.7 to a newer QEMUs. SSDT table size in QEMU-1.7 doesn't change regardless of a number of PCI bridge devices present at startup. However in QEMU-2.0 since addition of hotplug on PCI bridges, each PCI bridge adds ~1875 bytes to SSDT table, including pc-i440fx-1.7 machine type where PCI bridge hotplug disabled via compat property. It breaks migration from "QEMU-1.7" to "QEMU-2.[01] -M pc-i440fx-1.7" since RAMBlock size of ACPI tables on target becomes larger then on source and migration fails with: "Length mismatch: /rom@etc/acpi/tables: 2000 in != 3000" error. Fix this by generating AML only for PCI0 bus if hotplug on PCI bridges is disabled and preserves PCI brigde description in AML as it was done in QEMU-1.7 for pc-i440fx-1.7. It will help to maintain size of SSDT static regardless of number of PCI bridges on startup for pc-i440fx-1.7 machine type.

2014-07-28pc: hack for migration compatibility from QEMU 2.0Paolo Bonzini4-4/+78
Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

2014-07-28acpi-dsdt: procedurally generate _PRTPaolo Bonzini3-1832/+128
This replaces the _PRT constant with a method that computes it. The problem is that the DSDT+SSDT have grown from 2.0 to 2.1, enough to cross the 8k barrier (we align the ACPI tables to 4k before putting them in fw_cfg). This causes problems with migration and the pc-i440fx-2.0 machine type. The solution to the problem is to hardcode 64k as the limit, but this doesn't solve the bug with pc-i440fx-2.0. The fix will be for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the ACPI tables. First, however, we must make the actual AML equal or smaller; to do this, rewrite _PRT in a way that saves over 1k of bytecode.

After commit f702e62 (serial: change retry logic to avoid concurrency, 2014-07-11), guest boot hangs if the backend is an unconnected PTY. The reason is that PTYs do not support G_IO_HUP, and serial_xmit is never called. To fix this, simply invoke serial_xmit immediately (via g_idle_source_new) when this happens.

2014-07-22vmstate_xhci_event: fix unterminated field listLaszlo Ersek1-0/+1
"vmstate_xhci_event" was introduced in commit 37352df3 ("xhci: add live migration support"), and first released in v1.6.0. The field list in this VMSD is not terminated with the VMSTATE_END_OF_LIST() macro. During normal use (ie. migration), the issue is practically invisible, because the "vmstate_xhci_event" object (with the unterminated field list) is only ever referenced -- via "vmstate_xhci_intr" -- if xhci_er_full() returns true, for the "ev_buffer" test. Since that field_exists() check (apparently) almost always returns false, we almost never traverse "vmstate_xhci_event" during migration, which hides the bug. However, Amit's vmstate checker forces recursion into this VMSD as well, and the lack of VMSTATE_END_OF_LIST() breaks the field list terminator check (field->name != NULL) in dump_vmstate_vmsd(). The result is undefined behavior, which in my case translates to infinite recursion (because the loop happens to overflow into "vmstate_xhci_intr", which then links back to "vmstate_xhci_event"). Add the missing terminator.

commit e938ba0c tried to enable -mem-path for ppc but breaked some ppc boards. The problems are: 1. it fails when allocating memory for rom, sram whose sizes are less than huge page size: ./ppc-softmmu/qemu-system-ppc -m 512 -mem-path /hugepages/ \ -kernel /home/hutao/Downloads/vmlinux-ppc -initrd \ /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed. 2. if there is a numa node backed by memory backend object, qemu fails with message: ./ppc-softmmu/qemu-system-ppc -m 512 \ -object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \ -numa node,nodeid=0,memdev=f0 \ -kernel /home/hutao/Downloads/vmlinux-ppc \ -initrd /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value. This patch does following: 1. replaces memory_region_allocate_system_memory() with memory_region_init_ram() for rom, sram. Then only system memory is backed by hugepages when specifying mem-path. 2. for memory banks, allocates all ram with one memory_region_allocate_system_memory(), and use memory_region_init_alias() to initialize memory banks.

2014-07-22virtio-rng: Add human-readable error message for negative max-bytes parameterJohn Snow1-1/+7
If a negative integer is used for the max_bytes parameter, QEMU currently calls abort() and leaves behind a core dump. This patch replaces the abort with a simple error message to make the reason for the termination clearer. This also ensures device-hotplug with invalid input doesn't cause qemu to quit. There is an underlying insufficiency in the parameter parsing code of QEMU that renders it unable to reject negative values for unsigned properties, thus the error message "a non-negative integer below 2^63" is the most user-friendly and correct message we can give until the underlying insufficiency is corrected.
